Based on quarterly average exchange rates during the three months ended December 31, 2016.

Investment Activity

Digital Realty did not close any acquisitions, dispositions or joint venture contributions during the fourth quarter of 2016.

Earlier in the year, Digital Realty closed the previously announced acquisition of a portfolio of eight high-quality, carrier-neutral data centers in Europe in a transaction valued at $874 million (based on the exchange rate at the date of announcement). In addition, Digital Realty also acquired four land parcels in Ashburn, VA, Franklin Park, IL and Garland, TX for a total purchase price of $48 million in 2016.

Separately, Digital Realty also completed the sale of six assets in various markets during 2016 for total net proceeds of $360 million.

Balance Sheet

Digital Realty had approximately $5.8 billion of total debt outstanding as of December 31, 2016 substantially all of which was unsecured. At the end of the fourth quarter of 2016, net debt-to-Adjusted EBITDA was 4.8x, debt-plus-preferred-to-total enterprise value was 30.3% and fixed charge coverage was 3.9x.

During the fourth quarter of 2016, Digital Realty pre-paid $108 million of secured debt. Subsequent to year-end, Digital Realty retired the $50 million Series E Prudential Unsecured Senior Notes at maturity in January 2017.

As of year-end, 2.375 million shares remained subject to the forward sales agreement originally entered into during the second quarter of 2016. The remainder of the forward sales agreement is expected to settle no later than May 19, 2017.

2017 Outlook

Digital Realty reiterated its 2017 core FFO per share outlook of $5.90 - $6.10. The assumptions underlying this guidance are summarized in the following table.

The "same-capital" pool includes properties owned as of December 31, 2015 with less than 5% of the total rentable square feet under development. It also excludes properties that were undergoing, or were expected to undergo, development activities in 2016-2017, properties classified as held for sale, and properties sold or contributed to joint ventures for all periods presented.

For all periods presented, we have excluded the effect of dilutive series E, series F, series G, series H and series I preferred stock, as applicable, that may be converted upon the occurrence of specified change in control transactions as described in the articles supplementary governing the series E, series F, series G, series H and series I preferred stock, as applicable, which we consider highly improbable.

Relates to earn-out contingencies in connection with the Sentrum and Singapore (29A International Business Park) acquisitions. The Sentrum earn-out contingency expired in July 2015 and the Singapore earn-out contingency will expire in November 2020 and will be reassessed on a quarterly basis. During 2015, we reduced the fair value of the earnout related to Sentrum by approximately $44.3 million. The adjustment was the result of an evaluation by management that no additional leases would be executed for vacant space by the contingency expiration date.

For definition and discussion of EBITDA and Adjusted EBITDA, see below.

Definitions

Funds from Operations (FFO):We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of property, excluding a gain from a pre-existing relationship, impairment charges, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs' FFO. Accordingly, FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Core Funds from Operations:We present core funds from operations, or core FFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate core FFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) transaction expenses, (iii) loss from early extinguishment of debt, (iv) costs on redemption of preferred stock, (v) change in fair value of contingent consideration, (vi) severance-related expense, equity acceleration, and legal expenses, (vii) bridge facility fees, (viii) loss on currency forwards and (ix) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of core FFO as a measure of our performance is limited. Other REITs may not calculate core FFO in a consistent manner. Accordingly, our core FFO may not be comparable to other REITs' core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Adjusted Funds from Operations (AFFO):We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from core FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount/premium, (iv) non-cash stock-based compensation expense, (v) non-cash stock-based compensation expense, (vi) straight-line rent revenue, (vii) straight-line rent expense, (viii) above- and below-market rent amortization, (ix) deferred non-cash tax expense, (x) capitalized leasing compensation, (xi) recurring capital expenditures and (xii) capitalized internal leasing commissions. Other REITs may not calculate AFFO in a consistent manner. Accordingly, our AFFO may not be comparable to other REITs' AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

EBITDA and Adjusted EBITDA:We believe that earnings before interest, loss from early extinguishment of debt, income taxes and depreciation and amortization, or EBITDA, and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, change in fair value of contingent consideration, severance related expense, equity acceleration, and legal expenses, transaction expenses, gain (loss) on sale of property, gain on settlement of pre-existing relationship with Telx, loss on currency forwards, other non-core expense adjustments, noncontrolling interests, and preferred stock dividends. Adjusted EBITDA is EBITDA excluding change in fair value of contingent consideration, severance related expense, equity acceleration, and legal expenses, transaction expenses, gain (loss) on sale of property, gain on settlement of pre-existing relationship with Telx, loss on currency forwards, other non-core expense adjustments, noncontrolling interests, preferred stock dividends and issuance costs associated with redeemed preferred stock. In addition, we believe EBITDA and Adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA and Adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, exclude capitalized costs, such as leasing commissions, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do; accordingly, our EBITDA and Adjusted EBITDA may not be comparable to such other REITs' EBITDA and Adjusted EBITDA. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income computed in accordance with GAAP as a measure of our financial performance.

Net Operating Income (NOI) and Cash NOI:Net operating income, or NOI, represents rental revenue, tenant reimbursement revenue and interconnection revenue less utilities expense, rental property operating expenses, repair and maintenance expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company's rental portfolio. Cash NOI is NOI less straight-line rents and above and below market rent amortization. Cash NOI is commonly used by stockholders, company management and industry analysts as a measure of property operating performance on a cash basis. However, because NOI and cash NOI exclude depreciation and amortization and capture neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of NOI and cash NOI as measures of our performance is limited. Other REITs may not calculate NOI and cash NOI in the same manner we do and, accordingly, our NOI and cash NOI may not be comparable to such other REITs' NOI and cash NOI. Accordingly, NOI and cash NOI should be considered only as supplements to net income computed in accordance with GAAP as measures of our performance.
